a study was carried out to investigate the effects of organic acid mixture as well as two methionine supplements on performance, carcass characteristics and weight of gastrointestinal tract in broiler chickens. six hundred unsexed day-old ross 308 broiler chicks were utilized in a factorial arrangement of treatments (3×2) based on completely randomized design (crd) of 4 replicates of 25 chicks ...

Abstract Filler’s presence in hot-mix asphalt (HMA) is even though minimal but they do affect its durability characteristics. Many natural and waste materials the form of fillers have been studied for their effectiveness on HMA mix design performance However, practice, stone dust (SD) preferred filler due to abundance, ease availability, cost-effectiveness. Thus, major objective this study was ...
